Spindash dust
Charging a spindash kicks up dust, we all know this feature was dying to get in at some point. Bubble and flame forms of spin dust are included from FSonic, for underwater and elemental respectively.
Oh, and as a bonus I reorganised the spindash/spinning/other ability2 stuff code to look a bit neater and more organised.
New resources:
* MT_SPINDUST - the object
* S_SPINDUST1 to 4 - the normal form's states
* S_SPINDUST_BUBBLE1 to 4 - the bubble form's states
* S_SPINDUST_FIRE1 to 4 - the bubble form's states
* SPR_DUST - the normal form's sprite set (uses frames A to D, just pinch FSonic's sprites really)
* SPR_FPRT - the flame form's sprite set (frame A only)
SF_NOSPINDASHDUST disables spindash dust for a character

Sprite2 changes
Some stuff!
* Lua access to sprite2.
* Introducing new Lua-exclusive function, P_IsValidSprite2(mo, spr2). Basically just a wrapper for (((skin_t *)mobj->skin)->sprites[spr2].numframes > 0), useful for creating custom sprite2 defaulting functions since hooking into P_GetMobjSprite2 wouldn't be worth it.
* FF_ANIMATE support for sprite2s. The var2 of the state works identically to normal FF_ANIMATE, but var1 is completely disregarded - it just runs all of the frames available to that one sprite2 animation set.
* As a result, a bunch of states which were either not previously animatable or had animated at constant speed now get animation without state changes.
* P_SetMobjState now supports sprite2 defaulting like P_SetPlayerMobjState does.

Damage control + Match rebalancing
This is two branches in one since while I was working on damage-control's changes months back, I felt it was best Match rebalancing was merged in here too (thanks JTE for helping me do so).
Changes from damage-control:
* `player->health` (formerly the "HUD copy" of `player->mo->health`) is now `player->rings`, and is also now the player's actual ring count.
* `player->mo->health` (formerly rings + 1) is now always 1 when alive, regardless of ring count; if player with rings is damaged, this is untouched.
* P_RingDamage now includes ring spilling code.
* P_ShieldDamage now has a damagetype argument, allowing me to remove the last MT_NULL hack left in from the pre-damagetype days that I forgot about.
* The old "switch-to-seestate" enemy damaging behavior in P_DamageMobj has been removed. This was a Doom left-over and doesn't really affect SRB2's enemies anyway - see, Doom enemies had a random chance of using seestate or painstate, SRB2 enemies always use painstate.
* Other minor efforts to reorganise damaging code and have it make more sense, but otherwise nothing that should affect gameplay in general.
Changes from match-rebalancing:
* New weapon/ammo dropping behavior: if you have the weapon panel + ammo, you drop the panel (but not the ammo); if you don't, you just drop the ammo.
* New Match ammo consumption: Weapon rings can now be fired with no rings at double the ammo cost.
* New emerald behaviour: collecting all 7 emeralds no longer turns you super (read: Match super is dead now) but instead steal points from enemies and gives you and teammates invincibility + sneakers
* Tails ringslinger buff: Any character with CA_FLY will now throw rings 1.5x as fast.

* All Lua-originated sprite2 settings are now forced through P_GetMobjSprite2. Makes sense because of SPR2_JUMP, which none of the main characters have sprites for yet all use.
* Cleaned up P_GetMobjSprite2 to not set irrelevant, otherwise-unused variable.
Fixed players disappearing when spindashing whilst wearing multi-layer shields

The problem was that MT_OVERLAY's default radius and height were never getting changed from 1*FRACUNIT, and that meant that when you spindashed, the game considered it completely below the surface of the flat you were standing on. Since you're not usually clipped on flats that don't belong to FOFs, we didn't notice this aspect of the issue sooner.
(SORRY FOR THE MULTIPLE MR'S AGAIN I TOTALLY SUCK AT REMEMBERING TO MAKE SURE IT GOES TO NEXT INSTEAD OF MASTER)

* Bubblewrap shield bounce now no longer allows thokking post-bounce, but still allows bouncing
* plus a bunch of tiny changes to clean up code around the place.
* Some shield sounds swapped (can be reverted later).
* Partial implementation of S3K shield abilities.
* The ability to elemental-groundpound onto gold monitors without going straight through them.
* Force shield ability removed because nobody could agree on it, we'll keep it blank until another idea can get through the disagreement juggernaut.
* shields give you 1000 points
* redundant shields don't make you puase
* checkpoints give you 2000 points
* falling down a deathpit is just falling, not bouncing
